The common ion is chloride (Cl-).
Nothing
The constant solubility product is modified.
When a solute is added to a solvent until no more dissolves, the solution is said to be saturated. In some cases a solution can be made to be supersaturated by temporarily increasing the solubility of the solvent, such as through an increase in temperature.
lowering of solubility of the first solution when an another solution is added having the same ions is called common ion effect.
because the saturated solution dont dissolve
Solution provided the solution is not saturated.
A saturated solution is made when you have added so much solute that no more dissolves. The amount of solute needed to make a saturated solution will change with the temperature of the solution.
The concentration of the salt solution does NOT change- it is saturated.
A saturated solution is a solution that no more solute will dissolve. Once the solution is saturated, any more solute that is added will not dissolve.
If more solute is added to the solution and the solute remains undissolved, then you know that solution is saturated.
From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.
A saturated solution is a solution that no more solute will dissolve. Once the solution is saturated, any more solute that is added will not dissolve.
NOTE: THIS IS NOT THE SAME AS SODIUM BICARBONATE! See the Related Questions for the solubility of baking soda.This is from the website linked to the left of this answer under Web Links: Solubility:45.5 g/100 ml water @ 100 °C (212 °F)Therefore, at that temperature (note that it is high!), in 1 liter, 455.0 grams of Na2CO3 will dissolve to make a saturated solution.
